Dataflows & Gateway Permissions

Hi,

 

We have a SQL Data Warehouse...users have access to it which restricts them to be able to see certain data.  They can build reports and publish them to the service.

We have a Gateway set up and have created a datasource pointing to the Data Warehouse using credentials that can see everything.

We give relevant users access to the gateway datasource so that they can schedule refreshes on their datasets.

 

Problem I'm seeing is if they were to create a dataflow connecting to that server & database they can then see everything in the datawarehouse, it isn't restricted as they can use the gateway datasource to connect.

Is my understanding correct?  How could this be avoided other than by trying to implement SSO or is that the only way?

 

Thanks

    Hi Anonymous ,

     

    From what you have shared - I believe the users are able to see everything because the credentials used for the gateway are allowing all data to pass into the power bi service. So if the end user were to use that Gateway to create a Dataflow that connects back to your SQL Server & Db, it will bring back everything. 
    Best practice here would be to build a dataset with RLS and share that with end users. Let them build reports off the dataset instead of them creating a dataflow to get access to the data. 
    RLS will ensure that the data gets filtered and users can only see the data that they have access to.

      Thanks, but if only it were that simple!

       

      This is a 'legacy' warehouse that has hundreds of tables spanning lots of different business areas, not feasible to combine it all in one nice dataset.  The analysts using it are used to connecting directly to it and then adding data from other sources to build their datasets and reports. 

       

      I want them to be able to create dataflows but ideally not from this data source.  I wish there was a way of specifying in the Gateway Data Source User permissions whether to allow use for Dataset Refresh and/or Dataflow use. 

       

      I think there is an issue with the current documentation; it only mentions dataset refresh when creating users, there is no mention that it will also allow dataflow use too.

        Hi Anonymous ! 

         

        Your analysts should build their reports and datasets in Desktop by collating the data sources as they normally do. When you publish to the service, the Gateway's job is to connect the existing queries to it's source using the stored credentials in the pbix file. The credentials used will be the same as the one the team of analysts currently use to build the report in Dekstop. 

         

        As of this date, Dataflows are currently not able to do what you would like. You can try to use the method I suggested and wait for future product releases and watch the idea blog to see if it gathers any traction.
